One simple way of calculating gas mileage of your vehicle is to keep a check on odometer reading. Alternately, you can reset mileage counter at the time of getting your gas tank filled. Find out the mileage that accrued between two gas fills depending on your odometer reading, alongside the price for each gallon. After that divide the figure of mileage with the number of gallons you got filled second time for obtaining mileage per gallon. But you can use this gas mileage calculator here as well for determining the mileage of your vehicle without getting into any kind of hassles.
If you are too concerned about the mileage efficiency, there are quite a few options that you can try for improving your vehicle's gas mileage. Let's take a look at few of them.
1. First of all, you should have a vehicle that is fuel-efficient. There are government resources available online that give you everything you need on comparing different vehicles for their fuel efficiency. Try to avoid 4-wheel drive vehicles as their fuel efficiency is low as compared to RWD or FWD. Powering all the wheels requires the engine to work harder.
2. Gas mileage is often reduced if the tires are under-inflated. There's 0.3 percent/PSI drop because of wasteful energy transfer as it dissipates into tire's mushiness when they're underinflated. Rigid tires always make for better frictional interaction of road and the rubber and this leads to forward momentum.
3. Fuel efficiency is also related to speed as well. If the speed limits do not stop you, make sure that you keep it at 55 MPH for best fuel efficiency.
4. In order to increase the fuel efficiency of your vehicle, you should try to keep it running steadily and consistently. The engine has to work harder if you opt for aggressive acceleration and this drain off more oil. So, it is always better to accelerate the vehicle steadily to keep it more fuel efficient.
5. You can also make your vehicle consume less gas by keeping it in good shape. Use recommended motor oil for having 1 to 2 percent improvement in gas mileage. Check the driver's manual for your vehicle and see what's recommended. Also, keep your vehicle's engine tuned properly, maintain oxygen sensor properly and solve the failed emissions test immediately. Air filters should also be checked every couple of months to avoid clogging of any kind.
6. If there is any kind of unnecessary weight, it should be removed right away. It's simple physics, heavier objects require more energy to be moved. So, when you have to achieve greater fuel efficiency, it is advised to drive a smaller and lighter vehicle. Shedding any extra weight off your car can also help. Anything heavy that is unnecessary should be taken off the car. Big subwoofers can be a good example of this.
7. Most of the times, you experience poor fuel economy during particularly hot climates due to oil partitioning needed for powering the AC of the vehicles' cabin. AC usage can reduce fuel economy by around 25 percent. So, try not to keep the air-conditioner unnecessarily high, particularly when your vehicle is idle.
There are four values that you have to provide for this gas mileage calculator to work. Enter the current and previous odometer reading, the gas gallons used, and the gas price. Besides, you can choose between the Metric and the US units. Once you have provided all these values, you can hit the calculate button and the results will be shown instantly.
The gas mileage calculator shows you the gas mileage your vehicle is giving per gallon, mileage travelled so far after last refill, the filling expense, and the unit cost that you have to bear per mile. All this information is quite useful and can be utilized for taking proper action to increase the gas mileage of your vehicle.
